Synopsis

Dilated pore of Winer (or dilated pore) is a benign adnexal tumor with differentiation toward hair structures. It is a common lesion that may be acquired due to inflammatory cystic acne or actinic damage. Clinically, the condition appears as a solitary, enlarged pore filled with keratin, most commonly situated on the head and neck, but it can also be seen on the trunk of middle-age to elderly adults. The cavity is filled with lamellar keratin, and patients will often report expression of white, caseous keratin debris from the pore that will refill over several weeks.

Although typically asymptomatic, inflammation or infection may occur with manipulation.
